Abstract: SEISMIC SOURCE ARRAY FIRING CONTROLLER  ABSTRACT OF THE DISCLOSURE         There is disclosed apparatus for controlling the precise time of firing of each air gun in an array of air guns employed in marine seismic exploration.  For each air gun in the array, the apparatus maintains a record of past measured gun delays, that is the time period expiring between the triggering of an air gun and the time that the gun actually fires.  Upon the receipt of a fire command, the apparatus inserts appropriate delays before triggering the individual air guns.  In this way the air guns are controlled to fire in a precise predetermined sequence.  The air guns may be caused to fire either simultaneously or sequentially so as to exercise effective control over the spectral content and the directionality of the energy generated by the array.

Abstract: ABSTRACT OF THE DISCLOSURE          The impact resistance of rigid polymeric resins (e.g. PVC, SAN, PMMA, etc.,) is enhanced by the incorporation therein of an improved toughener.  This toughener comprises three distinct phases:  (a) a core of thermoplastic or thermo-set resin having a Tg below room temperature, (b) a rubber-like layer overpolymerized on the core, and (c) a relatively hard polymer layer overpolymerized on the rubber layer.  The utilization of a "soft" core, or seed, apparently enhances the efficiency of the toughener in the rigid polymer.  In one of the preferred embodiments of this invention, the improved toughener comprises a seed derived from a partially cross-linked poly(n-butylacrylate), a rubber-like (or intermediate) layer derived from a monomer mixture containing n-butylacryl-ate and an addition monomer and an outer layer (or shell) derived from a monomer mixture containing styrene and methyl-methacrylate.
